How Double Glazed Windows Are Rated For Efficiency

Many homeowners have come to realise that it is wise to invest in double-glazed windows for their home. They will last for a long time and can give you better energy efficiency than standard windows. This can, in turn, lower cooling and heating bills and is better for the environment. Many consumers want to know how these window versions are rated for efficiency and whether all products are similar. They may also wonder about triple glazing and whether it is better than the others.

How They’re Rated

Your area or country likely has a council that is charged with labelling and grading all windows sold there based on how energy efficient they are. They can help you find honest, correct, and thorough ratings that will help you decide which products to choose for your home.

The Grading System

Windows are usually assigned a grade from A to E, where A is the highest grade possible, and E is the lowest. They provide rigorous tests on the product to see how well it conserves and contains heat within the home, all while allowing the sun to shine through and provide you with free heat. Once they’re finished with their tests, they will grade and label the product with their findings. Most grading systems also include the ability to block wind, sound, and condensation, as well.

Is Everything The Same?

In a nutshell, no, not all double glazed windows are the same. It is up to you to determine the highest grades available, and potentially, have them installed by Central Glass & Aluminium. They may be slightly more expensive but will ensure that your home performs better and can help you reduce the cost and usage of energy in your home.
